NOTE: you could stop the cluster on each node by using below commands

# crsctl stop crs -f

# crsctl start crs -excl -nocrs

‘-nocrs‘ option introduced with 11.2.0.2 prevents the start of the ora.crsd resource. It is vital that this optionis specified; otherwise the failure to start the ora.crsd resource will tear down ora.cluster_interconnect.haip, which in turn will cause ASM to crash.
